JetBlue cancelled my reservation and provided refund to my CC that was closed before. So the bank returned refund. I have transactions ID. JetBlue is not responding to any channel of communication now answering all the time "we already refunded". Whom should I reach to locate funds in JB account and to get the refund processed? The funds are on JetBlue account in their bank - their Customer Service Agents even don't try to understand the problem if I reach them by email or twitter.
